To all whom it may concern:

Be it known that l, ARTHUR W. EASTWOOD, a citizen of the United States, residing at Alden, in the county of Erie and State of New York, have invented certain new and useful Improvements in Fuel-Heating Devices, of which the'following is a specification.

The'present invention relates to improvements in heating devices designed as an attachment for the manifold of an internal combustion engine by means of which heated gases, preferably taken from the engine exhaust, may be utilized, to impart heat to the fuel conveying passage for the purpose of materially assisting in effective vaporization of the carbureted fuel.

The device embodies a chambered body detachably mounted on the intake manifold and having a conduit leading thereto from the exhaust manifold so that a portion of the exhaust gases will pass through the body and in so doing heat the wall of the body which contacts with the surface of the manifold, this arrangement having special advantages pointed out more clearly hereinafter.

Fora full understanding of the present invention, reference is to be had to the following description and the accompanying drawing, in which:

ll igure l is an elevation showing the ap EllllfltlOIl of this invention to the manifold of engine, parts being broken away and shown in section.

l 2 is a sectional view taken substanlly on the plane indicated by the line 2-2 3 is a perspective view showing a slightly modified form of holding means for the device.

llip l is a rear elevation.

lPhroughout the following detail description, and on the several figures the drawing, similar po ts are referred to by like reference charact rs.

Referring the drawing it designates the intake manifold, and ll the exhaust manifold a conventional type of internal combustion engine. To an intermediate portion of the former, the device which forms the subject matter of this intention is preferably attached and said device consists of a hollow body 1 of substantially it-shaped configuration, the inner wall 2 of which contacts with the manifold ll. when the body is properly positioned in place and the ends of said body extend sufliciently around the manifold to so Specification of Letters Patent.

cure the maximum amount of heating surface While yet enabling the device to be slipped on and oft of the manifold. The body is preferably held at the desired position by means of a set screw 3 which extends through one end of the body as shown most clearly in Fig. 2 and engages with the manifold to lock the member 1 in place. The exhaust manifold B of the engine is tapped at a suitable place above the member 1 and a conduit or pipe 4 is connected thereto at one end and to the member 1 at the other so as to establish communication between the exhau-st manifold and said member. The body is provided furthermore with an outlet 5 preferably located at the opposite end of the body to that into which the' conduit leads so that the eases which pass from the exhaust manifold into the heating; chamber 6 will necessarily have to follow completely around the chamber to the other side before escaping. This movement of the heats the inner wall 2 quite materially and said wall transmits its heat to the wall of the intake manifold A. The carbureted fuel which is injected into the manifold A in most instances and especially during cold weather is only partially vaporized and in passing the heated surface of the manifold when this device is in place such fuel is heated and introduced into the engine in a much better eondition for affording," proper combustion therein. it is to be understood the direct li cation of heat to the wall of the inanifo l A is not entirely desirable because the fact that the direct heating in this manner is likely to cause premature combustion of the fuel in said manifold. The that only a portion of the exhaust gases from the manifold B are into this chambered body 1 and must become effective through the inner wall of said body as well as the wall of the manifold, provides a moderated heat which is an important phase of my device.

'iitly liflln Fig. 3 l have illustrated a s ferent form of fastening means for holding" the member upon the manifold. ln this instance I provide a plate 3 which is attached by suitable fastening membes 3* across the ends of the body thus inclosinp," the manifold.

uds to pre- "Ill ice

Having thus described my invention, what I claim as new is:

The combination with intake and exhaust manifolds of an internal combustion engine,

5 of a heating attachment adjustably connect- 10 ject slightly beyond the side of said manifold, a conduit establishing communication between the exhaust manifold and the interior of the body, the body having an outlet and means for adjustably holding the body of the manifold comprising a yieldable plate member connected across the ends of the body, said plate having frictional contact with the manifold for holding the device in place thereon.

In testimony whereof I afiix my signature. 20
